When the ambient temperature is below -0°C, both the multi-layer fabric conveyor belt and the steel cord structure conveyor belt begin to lose their elasticity. As the temperature continues to drop, the covering rubber will continue to lose its flexibility and resistance to wear, impact and cutting. The conveyor belt will also become so hard that it cannot pass through or bypass the drums and pulleys, which will eventually cause the rubber covering and the rubber inside the carcass to break.
The rubber conveyor belt from swelling and softening when it comes in contact with greasy or mild oily materials, contributing to belt deterioration. Therefore, oil resistant conveyor belts must be selected for conveying materials containing oil or grease.
Rubber conveyor belt in high temperature conditions will accelerate aging, resulting in rubber hardening and rupture. Heat also has a seriously harmful effect on the belt carcass itself because it damages the adhesion between the cover and the carcass and between the fabric plies contained within the carcass. This actually breaks the belt. Therefore, it is necessary to choose heat resistant rubber conveyor belt.
Conveyor belts are usually made of leather, fabric and rubber. Some rubber conveyor belts use a ply of fabric and cover the rubber. Most conveyor belts are made of two or more ply of fabric or other materials.
Applications such as quarries, aggregate production or mining operations require the transportation of large amounts of heavy, sharp, hard, and highly abrasive materials. Even the strongest conventional conveyor belts can be torn and worn by large, heavy and sharp materials within weeks or months. Therefore, the heavy-duty rubber belts used in the aggregate and mining crushing industries need to have high tear resistance, impact resistance and wear resistance.
Aggregates are building materials used in construction, including sand, gravel, crushed stone, and recycled concrete. Aggregates are consumed in private residential construction, commercial construction, urban and infrastructure construction. The conveying system is inseparable from raw material mining, crushing processing to finished aggregate transportation. High-quality aggregate conveyor belts can improve the efficiency of aggregate processing in quarries and save costs.
